Correlation of body composition parameters using different methods among Brazilian obese adults
The objective of this study was to correlate anthropometric, BIA and DXA parameters among obese Brazilian adults with focus on the comparison with visceral adipose tissue (VAT) obtained from DXA and in the value of antropometric measurements. Fifty voluntary participants were enrolled. The Spearman correlation test was used to assess the correlation of VAT with anthropometric measurements, BIA and other DXA parameters. The intra-class correlation coefficient (ICC) was used to evaluate concordance between lean mass (LM), fat mass (FM), %body fat (%BF) and %upper body fat (%UBF) obtained from BIA and DXA. Most were female (8...

Motor skills of children with autism spectrum disorder
The objective of this study is to describe variables of life habits associated with motor skills of children with autism spectrum disorder aged 8-10 years living in the city of Pelotas / RS. A questionnaire about lifestyle was applied and the Test of Gross Motor Development-2 (TGMD-2) was applied to assess motor skills. Independent T-test, ANOVA and Wilcoxon test were used to compare means. The study consisted of 49 individuals (42 males). The results indicate that the higher the level of ASD, the better the motor skills. Children making use of medications have greater deficits in motor skills. Higher scores on motor skill...

Comparison of maturation and physical performance in basketball athletes of different playing positions
Abstract The aim of this study was to compare the characteristics of somatic maturation, anthropometric and physical performance (vertical jump and aerobic power) in young basketball players of different playing positions (under 13 years) and analyze these relationships using Peak Height Velocity (PHV) as a measure of somatic maturation. For this, 26 male athletes were evaluated. Anthropometric variables were: body mass, standing and sitting height, and length of lower limbs. Maturation was determined by age at PHV. Physical performance was determined by lower limb power (counter movement jump - CMJ) and aerobic power (Int...

Body composition and performance variables differences in female volleyball players by agegroup and playing position
Abstract The aim of the present study was to evaluate the age and inter- and intra-position differences in the anthropometric variables and physical performance in young female players of Brazilian women's volleyball. Fifty-eight female volleyball players participated, divided into 3 age groups: (a) 14 and under (n=20; mean age = 12.6 ±0.7 years), (b) between 14 and 17 (n=31; mean age = 15.6±1.2 years), and (c) over 17 (n=7; mean age = 18.9±0.9 years). In addition, the players were also divided according to their positions: setters (n=7), opposites (n=13), passer-hitters (n=17), middle blockers (n=12) and liberos (n=9)....

Changes in developmental assets across a 4-month competitive season among youth basketball players
Abstract The present study examined the changes in developmental assets among young basketball players during a 4-month competitive period, accounting for variation by age group. Additionally, we examined the age-related variation on developmental assets. Sixty-five adolescent basketball players aged between 9.5 to 17.3 years were considered. We used the Portuguese version of the Developmental Assets Profile Questionnaire. Multilevel modeling was used to estimate the magnitude of changes on developmental assets across the 4-month competitive season, as well as aligning assets scores by chronological age. Positive values an...

Is technical performance related to the distance covered during U-19 futsal matches?
This study demonstrated that simulated futsal matches of the U-19 category present high physical demand, with values of distance covered per minute at different intensities similar to those found in professional Brazilian players during official matches. There were no significant correlations between physical and technical performance during matches; however, correlations classified as “ strong ” between unsuccessful kicks were obtained with total distance covered (r=0.51; p=0.06), distance covered at high intensity (r=0.51; p=0.09) and with distance covered in sprints (r=0.56; p=0.06), suggesting that the efficacy of...

Social support, self-efficacy and level of physical activity of students aged 13-15 years
Abstract The aim of this study was to verify the relationship, the population attributable fraction (PAF) and the relative risk reduction (RRR) of social support and self-efficacy with level of physical activity in students. Probabilistic cross-sectional study with 1,472 students aged 13-15 years. Gender, age, social support from parents and friends, self-efficacy and levels of physical activity were evaluated through questionnaires. Data analysis was performed using Poisson regression with robust variance, PAF and RRR, adopting p ≤ 0.05. A total of 56.1% (n = 826) of students were considered active, boys (68.7%) present...

Combined effect of physical activity and reduction of screen time for overweight prevention in adolescents
Abstract The main objective of this study was to identify the association between combined effect of physical activity, reduction of screen time and overweight in adolescents. The sample of this cross-sectional study consisted of 613 adolescents, aged 15-18 years living in a municipality in northeastern Brazil. Physical activity was measured using the short-version IPAQ (International Physical Activity Questionnaire), and screen time was verified through two questions about the time that, on average, interviewees watched television, played video games, used the cell phone or computer on a normal weekday and one weekend day...

Oxygen consumption and heart rate obtained in a ramp protocol are equivalent during exercise session of rectangular loading at ventilatory thresholds for athletes
This study tested if VO2 and heart rate (HR) corresponding to first (VT1) and second ventilatory threshold (VT2) determined during a ramp protocol were equivalent to those observed in rectangular load exercises at the same intensity in runners elite athletes (EA) and non-athletes (NA). Eighteen health subjects were divided into two groups: EA (n = 9, VO2max 68.6 mL ·kg-1·min-1) and NA (n = 9, VO2max 47.2 mL·kg-1·min-1). They performed CPx and 48h and 96h later, a continuous running lasting 1 h for VT1 and until exhaustion for VT2. The results showed that EA at VT1 session, presented delta differences for VO2 (+9.1%, p ...

Determination of heart rate threshold from heart rate kinetics during maximal graded exercise in soccer players
Abstract The main of the present study was to identify the heart rate threshold based on heart rate kinetics during graded maximal exercise in football players. Twenty-six male football players performed a maximal exercise test (Bruce protocol) on a motor-driven treadmill. Oxygen uptake (VO2) and heart rate (HR) were monitored, recorded and resampled at 3.5Hz. The ventilatory threshold (VT), and respiratory compensation (RC), heart rate deflection points (HRDP1 and HRDP2) and heart rate kinetics threshold (HRT) were determined by computerized methods. The heart rate variability (HRV) was assessed in the frequency domain. T...
